BED-PLATE I'OR BASE-BURNING WOOD-STOVE.

The Schedule referred to in these Letters Patent and making part of them To all whom it. may concern:

Be it known that 1, CHARLES D. Nnwron, of Troy, in the county ofRensselaer, and in the State of New York, have invented an provement inBase-Burning Wood-Stoves and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing, making a part of this specification, in which-Figure 1 is a vertical cross-section of astove, in which my improvementis shown as applied.

Figure2is a vertical longitudinal section of the same.

Figure 3 is a detached perspective view of my improvement.

Letters of like name and kind refer to like parts in each of thefigures.

My invention is an improvement upon a base-burning wood-stove, having adownward draught, invented by Elihu Horsford; and

It consists of a hollow bed-plate for supporting the fuel-chamber, theinterior of which serves as a flue for the admission of air into thefuel and combustion-chambers, for, the purpose of insuring more perfectcombustion, and also for the purpose of protecting said bedplate fromthe intense heat to which it is subjected.

In order to properly illustrate my invention, I will first,briefiyexplain the construction and operation of the aforesaid stove, (as shownin figs. 1 and 2,) and then proceed to describe my improvement.

In the annexed drawing- A represents the bottom,

B, the sides,

0 and O, the ends, and

D, the top of a box-stove of the usual form.

E represents the fuel-chamber, open at its bottom and front end, thelatter of which is secured to the front plate C, while its rear end issupported by legs,

resting upon the bottom of the ash-pit a.

Said fuel-chamber is somewhat smaller than the shell of the stove, sothat a space is left between them, E, which serves as a' flue for thepassage of the heated air to the chimney.

Extending around the base of the fuel-chamber E is a flue, e, to whichthe air is freely admitted, through openings in the front plate O.

G represents the grate, corresponding in size and shape to the base ofthe fuel-chamber, supported by legs, resting upon the bottom of theash-pit, its upper surface, at the edge, being very near to the base ofsaid chamber, so that sufiicient space only is left between them topermit of the passage of the gaseous products of combustion, and of theashes.

The grate is highest in the centre, and from thence slopes downward toeither side. The same incline is also given to'the rear end.

Secured directly beneath the grate, and corresponding in size therewith,is a plate of metal, H, between which and said grate is left asuificient space to allow a current of cool air to pass freely, for thepurpose of preventing the grate from becoming overheated.

The air is admitted through an opening, 0', in the front plate 0, and,after passingbetween said plate and the grate, mingles with the gas andsmoke from the fuel-chamber, and assists in insuring their combustion.

The door, I, isof the usual form and construction, being provided withone or more openings for the admission of air, which are closed, whendesired, by a slide.

The hearth, a, is made to close tightly.

Fuel being placed within the chamber, and ignited, the smoke and gas aredrawn downward, through the burning fuel,"into the space beneath thechamber, where they are met by a current of air passing out from betweenthe grate and plate H, and consumed, with the most intense heat, whichis so great as to cause much expense and trouble, from the frequentburning out of the base of said fuel-chamber, experience having provedthat the air will not circulate through the flue c with sufiicientrapidity to protect the base.

To obviate these objections, and also to secure more perfect combustionof the, gas and smoke, is the object of my invention, which consists ofa hollow bed-plate, K, upon which the fuel-chamber E is supported,having, upon the sides next the fuel-chamber and the flue F, a number ofsmall openings, k k, communicating with its interior, which, in turn,communicate with the open air, by means of suitable openings in thefront plate 0, or by hollow legs. I

The draught of the stove is sufficient to cause a strong current of coldair to pass through the bed-plate, so as to entirely preventoverheating, and, as the air passes into the fuel-chamber and flue F insmall jets, it is thoroughly mixed with the gas and smoke, and assistsmaplaced upon either or both sides of the base of the fuel-chamber.

The advantages claimed for this invention are, that it furnishes acomplete protection to the base of the fire-box, or fuel-chamber, andmuch lessens its cost, as, by its use, the flue around the base of saidfuelchamber can be dispensed with, and fire-brick used.

Having thus fully set forth the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is-- I Thewithin-described bed-plate, K, constructed and arranged substantially asand for the purpose shown. In testimony that I claim the foregoing, Ihave hereunto set my hand, this 4th day of January, 1869.
